Description

  The present invention relates to a technique for specifying a processing order in which a work-in-process part is input to each process.

  In order-made products such as industrial machines and motors, the production plan and manufacturing instructions must be determined in order to manufacture the product by the delivery date requested by the customer.

  For example, in Patent Document 1, in order to comply with the delivery date, the processing of in-process parts starts from the one with a small delivery time margin calculated by the ratio of the remaining processing time until the final process is completed and the remaining time until the delivery date. A technique for instructing manufacturing is described.

JP 2004-295679 A

  For example, in an assembly line where multiple sublines such as industrial machines and motors merge at the main line, large parts gather in the merge process, so there is a possibility that there will be no available space in the merge process, so the number of merge processes Is important.

  However, like the technique described in Patent Document 1, the technique for creating the processing order from the margin of delivery date does not consider the processing time until the merging process of each part, and the arrival time of each part is shifted. In some cases, not all parts are available. For this reason, in the merging process, the parts that have arrived first cannot start work, and the number of work in progress may increase.

  Therefore, an object of the present invention is to comply with the delivery date and reduce the number of devices in the merging process.

  In order to solve the above problems, in the present invention, in-process parts having a short delivery time are preferentially processed for products that have a short remaining processing time until the merging process.

  For example, the present invention is a manufacturing instruction device for specifying a processing order for putting in-process parts into each process, and includes order information for specifying a product and a delivery date of the product, a product, and a component constituting the product. , Part configuration information that identifies a process path for manufacturing the part, and a merging process that merges with another part that has passed through another process path in the process path, a process path, and a process included in the process path Process path information for specifying the processing time in the process, the product, the parts constituting the product, the process to which the part belongs, and whether or not the part is being processed in the process. A storage unit that stores work performance information to be identified, and a control unit, and the control unit, based on the work performance information, belongs to the process and processes the part that has not been processed in the process. Work in process A process that identifies the product, a process that identifies the process path of the work-in-progress part and the merge process from the part configuration information, and a process from the process path information to the merge process in the process path of the work-in-progress part. The remaining processing time until the merging process of the in-process parts is calculated, the remaining time until the delivery date of the product having the in-process parts is calculated, and the remaining time is calculated as the remaining processing time. A process for calculating a delivery margin by dividing, and for a work-in-process part in which the delivery deadline does not satisfy a predetermined threshold, a processing order is input to each process in order from the smallest delivery margin, and the delivery date For in-process parts with a margin greater than or equal to a predetermined threshold, the remainder of the parts constituting the product having a work-in-process part with a delivery margin greater than or equal to a predetermined threshold until the merging step And processing the minimum value of the time and processing order to introduce the widget part of a small product in each step in order, by performing, characterized.

  As described above, according to the present invention, delays in delivery can be reduced and the number of devices in the merging process can be reduced.

  FIG. 10 is a flowchart showing processing for specifying the processing order of components in progress in each process.

  First, the processing order calculation unit 121 reads the order information table 112a, the part configuration information table 113a, the process route information table 114a, the work performance information table 115a, and the parameter information table 116a from the storage unit 111 (S10).

  Next, the processing order calculation unit 121 creates a processing order of parts in each process up to the merging process (here, the assembling process) from the margin to the delivery date of the parts and the proximity to the assembling process. (S11). Details of the processing in step S11 will be described with reference to FIG. Moreover, what is necessary is just to make it process the order of processing of the components of each process after a confluence | merging process in order from arbitrary methods, for example, a thing with a small delivery date margin.

  Next, the processing order calculation unit 121 calculates the total number of work in process and the total work time of products (here, motors) in the merging process (S12).

  For example, the processing order calculation unit 121 refers to the part configuration information table 113a for records in which the start time is not stored in the start time column 115f in the work performance information table 115a, for each process in each process path of each product. By grouping together, the parts in progress in each process are specified.

  In addition, the processing order calculation unit 121 sets the motor j (j is a natural number assigned to each motor in order from 1 to identify the motor, and 1 ≦ j ≦ n). By specifying the processing time from the process time column 114d of the process path information table 114a to the process time until the assembly process of the parts in progress in each process, and summing the process time from the process in progress to the assembly process, The remaining processing time of the part in progress is calculated.

Then, the processing order calculation unit 121 sets MaxM _{j as} the maximum value of the remaining processing time until the assembly process of the parts in progress in each process in the set of all parts constituting the motor j, and the remaining processing time until the assembly process. Is the minM _j , the in-process time WT _j in the assembling process of the component i constituting the motor j (i is a natural number assigned to each component in order from 1 in order to identify the component) is (1 ).

  By this equation (1), the in-process time of each motor in the assembly process of the assembly line can be calculated.

Furthermore, when the total number of motors is n (n is a natural number), the total work time TWT _j of the motor is expressed by the following equation (2).

  By this equation (2), the in-process time of all products in the assembly process of the assembly line can be calculated.

  Further, the processing order calculation unit 121 calculates the total number of in-process motors in the assembly process using the interval time stored in the parameter information table 116a.

For example, when the current time is T, the interval time is ST, and the minimum value of the remaining processing time until the assembly process is set to MinM _{j in} the set of components constituting the motor j, the processing order calculation unit 121 (3) For the parts for which the equation is satisfied, the motor j is in the assembly process from time T to T + ST. By this equation (3), the total number of work in progress at each time interval ST in the assembly process of the assembly line can be calculated.

  Next, the processing order calculation unit 121 determines the margin to the delivery date calculated in step S11, the proximity to the assembly process, and the processing order of the parts, the total work time and assembly of the product in the assembly process calculated in step S12. The total number of products in process in the process is processed into a predetermined display screen and output to the output unit 124 (S13).

  FIG. 11 is a schematic diagram illustrating an example of the display screen 192. The example of FIG. 11 is an example when “processing order” is selected in a display selection area 192a described later.

  As illustrated, the display screen 192 includes a display selection area 192a, a process selection area 192b, and a processing order display area 192c.

  When “processing order” is selected in the display selection area 192a, a process for displaying the processing order is selected in the process selection area 192b, so that a work-in-progress part in the process (specified by the back part number and part name) is selected. The information for specifying the processing order is displayed in the processing order display area 192c together with the information for specifying the delivery margin and proximity.

  With such a display screen 192, the user of the manufacturing instruction apparatus 110 is processed according to the processing order and the processing order as reference information for resetting the delivery delay criteria stored in the parameter information table 116a. It is possible to refer to the margin until the delivery date of the part and the proximity to the assembly.

  FIG. 12 is a schematic diagram illustrating an example of a display screen. The example of FIG. 12 is an example when “in-process time” is selected in the display selection area 192a.

  As shown in the drawing, the display screen 192 includes a display selection area 192a, a total work time area 192d of the merging process, and a work time display area 192e.

  When “in-process time” is selected in the display selection area 192a, the total in-process time of the merging process is displayed in the total in-process time area 192d of the merging process, and the in-process time display area 192e displays each part of each product. Information specifying the process in progress and the remaining processing time until the merge process and the total work time of the product in the merge process are displayed.

  Such a display screen 192 allows the user of the manufacturing instruction apparatus 110 to use the product in-process time in the assembly process and the in-process time as reference information for resetting the delivery delay criteria stored in the parameter information table 116a. You can refer to the total work in progress of the product.

  FIG. 13 is a schematic diagram illustrating an example of a display screen. The example of FIG. 13 is an example when “total number of work in progress” is selected in the display selection area 192a.

  As illustrated, the display screen 192 includes a display selection area 192a and a total work-in-progress display area 192f.

  When “total work in progress” is selected in the display selection area 192a, the total work in progress display area 192f displays information for specifying the work in process time and the total work in progress for each product. .

  Such a display screen 192 allows the user of the manufacturing instruction apparatus 110 to display the total number of work in progress in the assembly process for each interval time as reference information when resetting the delivery delay standard stored in the parameter information table 116a. You can refer to it.

  Returning to FIG. 10, the user of the manufacturing instruction apparatus 110 refers to the display screen 192 to correct the total work time and the total number of work in progress if the user's evaluation criteria are satisfied (step S14). No), the process is terminated, and if the user's evaluation criteria are not satisfied, correction is made (Yes in step S14), and the process proceeds to step S15.

  In step S15, the processing order calculation unit 121 accepts input of correction of the delivery date reference value stored in the parameter information table 116a from the user of the manufacturing instruction apparatus 110 via the input unit 123, Return to and repeat the process.

  Here, the user of the manufacturing instruction apparatus 110 resets the value of the delivery deadline criterion to be small if importance is attached to the delivery date, and if the importance is placed on the work time and the number of work in progress, the delivery delay criteria. Reset the value to be larger.

  FIG. 14 is a flowchart showing the processing for creating the component processing order in step S11 in FIG.

  First, the processing order calculation unit 121 calculates a margin until delivery date for each part (S20).

For example, assuming that the remaining processing time P _i until the completion of the shipment process of the part i and the remaining time until the delivery date are T _i , the delivery date margin C _i is expressed by the following equation (4).

  Next, the processing order calculation unit 121 determines a component that is delayed in delivery from the value of the delivery delay reference value stored in the parameter information table 116a and the margin until the delivery date calculated in step S20 (S21). .

For example, assuming that the value of the delivery delay reference value is K and the delivery margin margin of the part i is C _i , the processing order calculation unit 121 is late from the delivery date if C _i <K, and observes the delivery date if C _i ≧ K. judge.

  Next, the processing order calculation unit 121 creates a processing order so that the parts determined to be delayed from the delivery date in step S21 are processed from those having a smaller delivery time margin calculated in step S20 (S22).

  Next, the processing order calculation unit 121 defines the minimum value of the work time until the merging process as the proximity among all the parts of the product that the part is determined to comply with the delivery date in step S21. Then, a process order is created so as to process from a part having a low degree of proximity, and in the case of a process having a process order created in step S22, a part having a low degree of proximity after the process order created in step S22. The processing order to be processed is connected (S23). By doing in this way, the processing order which reduces the work-in-time of the parts which arrive early at a confluence | merging process is attained.

For example, if the remaining processing time until the assembly process of the part i is M _i and the set of parts constituting the motor j is F _j , the proximity N _i of the motor until the assembly process is expressed by the following equation (5). .

  By this equation (5), the proximity of each product (each motor) in the assembly process (assembly process) of the assembly line can be calculated.

  For parts with the same value calculated by equation (5), the maximum value of the work time until the assembly process is defined as remoteness among all parts of the product, and processing is started from parts with low remoteness. As such, create a processing order. In this way, even between parts having the same value calculated by equation (5), a processing order that reduces the work time of parts that arrive early in the assembly process is possible.

For example, if the remaining processing time until the assembly process of the part i is M _i and the set of parts constituting the motor j is F _j , the remoteness D _i of the motor until the assembly process is expressed by the following equation (6). .

  From this equation (6), the remoteness of each product (each motor) in the joining process (assembly process) of the assembly line can be calculated.

  As described above, according to the present embodiment, it is possible to create a processing order in the product assembly line that complies with the delivery date requested by the customer and minimizes the number of in-process assemblies.
